Calculation of the free-free transitions in the electron-hydrogen scattering S-wave model
Chris Plottke, Igor Bray
The S-wave model of electron-hydrogen scattering is evaluated using the convergent close-coupling method with an emphasis on scattering from excited states including an initial sta…
Convergence of two-center expansions in positron-hydrogen collisions
Alisher S. Kadyrov, Igor Bray
The positron-hydrogen atom scattering system is considered within the S-wave model. Convergence in the elastic scattering, excitation, ionization, and positronium formation channel…
Spin-resolved electron-impact ionization of lithium
Igor Bray, Justin Beck, Chris Plottke
Electron-impact ionization of lithium is studied using the convergent close-coupling (CCC) method at 25.4 and 54.4 eV. Particular attention is paid to the spin-dependence of the io…
Integral cross sections for electron scattering by ground state Ba atoms
D. V. Fursa, S. Trajmar, I. Bray +4
We have used the convergent close-coupling method and a unitarized first-order many-body theory to calculate integral cross sections for elastic scattering and momentum transfer, f…
A study of cross sections for excitation of pseudostates
Igor Bray
Using the electron-hydrogen scattering Temkin-Poet model we investigate the behavior of the cross sections for excitation of all of the states used in the convergent close-coupling…
